Preparation method of barium diphenylaminesulfonate

The invention relates to a preparation method of barium diphenylaminesulfonate. The preparation method comprises 1, adding 5kg of diphenylamine into a container, adding 4L of concentrated sulfuric acid into the container, installing a stirring device and a pressure reduction device, carrying out stirring heating to a temperature of 155-160 DEG C, starting the pressure reduction device and carrying out pressure reduction for water distillation, 2, after sulfonation, adding water into the sulfonation product, wherein the volume of the water is 1-2 times that of the sulfonation product, carrying out hydrolysis, keeping a temperature of 120-125 DEG C for 20-30min, carrying out stirring, fast pouring the mixture into boiling water of which the volume is 10-15 times that of the mixture, adding a barium hydroxide hot solution which has a concentration of 50wt% and has the weight is 5-7 times that of the mixed solution into the mixed solution, carrying out thermal insulation and precipitation for 1-2h, carrying out filtration and respectively collecting filter residues and filtrate, and 3, carrying out washing and drying to obtain a product. A diphenylamine sulfonation direct synthesis method is used and barium hydroxide is used as a SO4 precipitating agent and an acid neutralizer so that deposition and neutralization are realized in one process and thus a cost is saved and work time is shortened.
